A second frame for supporting'the reservoir 3|! is pivotally mounted on the iirst'frame I2 in the following manner. This second frame consists generally of a pair of side members 32, preferably constructed of channels, and a pair of conventional cross braces 34. The front end of the side members 32 are provided with additional integral extensions 36 to the free ends of which are rigidly secured a pair of apertured lugs 38.

- To'the outer surfaces of the side members I6 ofthe first frame I2 and adjacent the vertical plates I8 are secured a pair of generally L-'shaped brackets 46 to which are secured a pair of vertical apertured plates 42 forming a channel 44 in which the lugs 38 are slid. A pair of suitable screw-threaded bolts 46 extend through the ver- -ticalplate 42 and the lugs 38 constituting a pivthrough transverse slots (not shown) to permit transverse or lateral adjustment of the pump on the bracket. One of the side members I6 of the first frame is provided With a pair of spaced longitudinal slots 54 through which extend suitable bolts 56 which engageably receive the side member ofthe bracket 50 to provide a means for lcngitudinally adjusting the brackets and pumps of the rst frame.

Y The pump, if it is not self-priming, is provided with a conventional primer can 58 and a driven shaft to which is secured a conventional pulley 60 which engages a second pulley 62 by means of an endless web or V-belt 64. The pulley 62 is made to engage the tractor or trailer power takeoff 66.

It should be mentioned at this point that the reservoir may be additionally supported on the second frame by means of conventional straps 68 which envelop the surface of the reservoir and which are secured by suitable bolts 'I0 to the side members 32 of the second frame. To the rear of the reservoir and resiliently mounted on the second frame, a conventional caster type wheel '|2 is provided. To the rear ends of the side members 32 of the second frame are suitably secured a pair of vertical brace members 'I4 interconnected, for better support, by means of diagonal cross braces '|6.y The top and bottom of each of the vertical braces 14 are provided with angles 18 for supporting a pair of vertical guide rails 86. A boom 82, in the form preferably of a substantially oblong block, is vertically adjustable upon the guide rails 80.by means of a pair of conventional clamps 85 having set screws 85'.

The boom is constructed of sections 84 and 86 in such manner as to permit vertical pivotal sprayer conduit 96.

movement of one section with relation to the other. This pivotal connection is accomplished in the following manner. A horizontal bar 88 is rigidly attached to one of the sections 84 at one extremity and at the other extremity is provided with an aperture for retaining a pivot pin which extends into the other section 86 of the boom. A suitable U-shaped'clamp 92 is welded to the horizontal bars 88 and serves to prevent section 84 from dropping and holds the sections 84 and 86 in proper alignment. A suitable bolt 94 extends across the top surface of the boom and engages the apertured free extremities of the upstanding arms of the clamp member 92. This bolt 94 must be removed when it is desired to pivot section 86 vertically relative to section 84 such as is necessary for the transport or roadable position. A sprayer conduit 96 is provided, preferably in the form of a flexible hose, which communicates by means of suitable conventional couples 98 with a plurality of sprayers |96 carrying conventional sprayer heads |92. The sprayer conduit and associated sprayers are rotatably and adjustably positioned on the boom 82 in the following novel manner. A plurality of substantially L-shaped apertured brackets |04 are bolted to the boom 82 at various desired positions. To the bottom horizontal leg |66 of the Ybrackets |94 is secured by means of welding or riveting a pair of spaced knuckles |98 in which is journalled the Intermediate the knuckles |68 on each'bracket a clamp I l0 is provided which carries a set screw II2 for securing said clamp to the sprayer conduit 96. The set screw I I2 is made to extend somewhat beyond the edge of the bottom leg |66 of the bracket |64 so that when the sprayer conduit and sprayer are rotated downwardly the set screw will abut the leg |06 and prevent further rotation of the sprayerconduit and sprayer thereon. Should the sprayers accidentally strike the ground, they will be automatically rotated upwardly, thus preventing any damage to the sprayers themselves.

Interconnecting the Yreservoir 30 and the pump 48 is a pump inlet conduit ||4 having a branch I I6 to which may be secured a pipe or hose which can be led into a well or a spraying liquid storage tank for drawing water or liquid into the reservoir. The'pump is further connected to a pump outlet conduit IIB. A fitting |20 having at least three passages, and preferably in the form of a three or four-way pipe couple, is secured through one of its passages to the conduit IIS); Through another passageway in the couple |28, a reservoir return conduit |22 is provided having a conventional pressure gage I24, and a valve |26. This valve |26 is opened when the operator desires to ll the reservoir with spraying liquid or water which is drawn into the reservoir via the branch conduit I I6. When it is desired to withdraw spraying liquid or water from the reservoir to ber conducted to the sprayers, the valve |26 is partially closed until the desired spraying pressure registers on the gage. The excess liquid is allowed to by-pass through valve |26 and provides agitation of the insecticide or herbicide spray liquid.

Communicating with the first passageway of the couple |20 is a liquid spray delivery conduit |28 having branches |30 and |32, respectively, each branch being provided with a suitable valve |34 and |36 for selectively opening and closingr either of the conduits.

In practical operation, the pump 48 is longitudinally adjusted on the first frame so that the pulley 62 can be made to engage the power take'- 5 off 6B of the tractor. By attaching a hose to the branch inlet l It, which hose is led into a spraying liquid storage compartment or well, the pump will draw this spraying liquid through the conduits I i4, then through the conduit I2 2 and finally into the reservoir 3G. In this phase or the operation, the valve 26 is opened while the valves |34 and 13S remain closed. After suiilcient liquid is stored in the reservoir 30the branch conduit llt is closed 01T. When it is desired to withdraw spraying liquid or water from the reservoir to be conducted to the sprayers, the valve 126 is partially closed until the desired spraying pressure registers on the gage. The excess liquid is allowed to by-pass through valve 126 and provides agitation of the insecticide or herbicide spray liquid. A spraying liquid will thereafter be pumped from the reservoir through the conduit H4, thence through the couple |22 and into the branches 136i and 32, ei ther together or selectively, and eventually to the spraying conduit and the sprayers Iii'i. As previously described, the boom which retains the spraying conduit .fifi and the associated sprayers |06 can be vertically adjusted and retained at any desired height. By providing a sectional boom, certain sections of the spraying conduit 98 and associated sprayers mi) may be vertically pivoted into any desired angulated position, as shown in Figure 4. And, lastly, the spraying conduit 98 and associated sprayers 122 may be rotated about the boom Thus, an extremely eiective spraying device is provided which is pivotally and resiliently mounted on a tractor or trailer, which is operated by means oi' a pump driven by the power takeofi" of the tractor and which is provided with sprayers which can be adjusted in virtually any and all positions for the eective delivery of desired spraying liquids.

In View of the foregoing description taken in 6 is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what claimed as new is:

l. An adjustable sprayer for use with a trailer comprising a boom, means for adjustably securing said boom on the trailer, spray nozsles interconnected by a exible fluid conveying conduit, and means for mounting said conduit on said boom for vertical pivotal movement, said mount ing means including a plurality of substantially L shaped brackets secured to said boom, a pair of spaced knuckles secured to each horizontal leg of said brackets, a clamp carried on each horizontal leg intermediate said knuckles, said conduit being journaled in and extending through said knuckles and ciamp, and means for securing said clamp to said conduit and iur preventing downward pivotal movement of said conduit beyond a predetermined position.
